Just got a new set of Gianelle Yerevans (22x9 up front and 22x10.5 in the rear)
Now I need to lower it. I decided to go with springs cause $$ and I don't think I need coilovers. With that being said what springs would you guys recommend and why??

Where's the best place to get lowering springs from? Ik there are several vendors but who has the best deal and good springs (hotchkis, pfadt, bmr)?

There are lots of good sponsors on here that you can buy parts from. I would look at places like Apex Motorsports, JDP, or Phastek Performance. We also sell direct so if you wanted to purchase a set of the BMR lowering springs it can be done directly through us.

I just looked on Chevy site, the LT is 160 pounds lighter than the SS. If you were to pull up on the fenders with 160 pounds and saw how much it rose, that's about how much the ride height may increase in the front. So the front end may ride a little higher than the back with the SS springs. In the past I've heard of people swapping 8 cylinder springs into a 6 cylinder model and it messed up the stance of the car. I don't know about the Gen V Camaro, but I would be concerned.

As far as bolt-on compatibility, I have no idea. They did revise suspension in 2012, specifically the rear sway bar end link locations. I don't know what else changed.
